Different subjects...you have animial list, How about a mamals list, A bird list, birds world wide, birds native to a specific country

No limit. Just creating a list on a subject is an interesting way to build learning. Yuo hit a letter you can't fill you'll be looking for information that will fill the gap. Guess what... do that you learn something, you may not find the gap filler in a hurry but you find a whole lot of other interesting informatin that may well create another list.
